I've recently started to get into sport from bouldering. There's a few crags near me in Sabino Canyon I'm interested in, but I was talking to a couple people at the gym and they said a lot of the hardware on those walls are older and probably not to be trusted. Does anybody in the area have a word or two to put in on these climbs? Could I trust them or talk to the people at the rec centre about rebolting those climbs?
